I am using the latest Frankenstein build from mgr.inc: Frankenstein_Base_1975_upto_2180

This is the instruction that I replaced for the hook:
movsx ecx,word ptr [eax*2+Battlecry.exe+199B60]
//Alt: db 0F BF 0C 45 60 9B 59 00
and not even this is accepted (even though it was generated by CE itself).

Is this a side-effect of using the Frankenstein build, or is this a real bug?
If the first, please ignore, if the second, please consider fixing it.
In the meantime, I'll try to find a different hook.
